{"version":"1.0","type":"rich","title":"Mobility Rate Bubble Chart","description":"This bubble chart visualizes mobility rates for California universities, plotting median parent household income against the percentage of students from the bottom income quintile who reach the top quintile. Circle size encodes average cohort size, while color indicates the change in parents from the bottom 40% over time. Built with D3 v5 and Vue, the SVG rendering uses `d3.scaleSqrt`, `d3.scaleDiverging`, and `d3.axisBottom`/`d3.axisLeft` to construct the chart, with data from Opportunity Insights.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/63d0eb707b014fdc90ebf4484eebb113?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
